Newtons first law
Newtons first law (seatbelt safety)
Newtons first law is an object at rest tends to stay at rest an an object in motion tends to stay in motion unless acted upon by an unbalanced force. For example, when a car is moving and then comes to an stop the care stops but you are still in motion if you dont have a seatbelt, if you have a seatbelt you would stop because the seatbelt held you back.
With Out Seatbelts
For example, If you dont have on a seatbelt and you get in a crash you could be flung throught the windshield
For example, if you wear a seatbelt you would pretty much be apart of the car so the seatbelt stops you from going throught the windshield.
